Demonstration Spherometer Subcategory_Weights and Masses the 90-45-45-degree faces redirecting wider

the 90-45-45-degree faces redirecting wider beams for total internal reflection and image-inversion work

gripping objects up to 90 mm and mounting to support rods up to 15 mm for chemistry and physics setups

the wider bore accepting full-size bar magnets while AC current drives the alternating field that rotates domains for demagnetization

supplying replacements when the originals lose loft or split during repeated charging cycles

Paired safety-socket outputs deliver two selectable ranges 0-70V and 0-125V DC at 300mA
